What happens if I run this as a service?

[chitkosarvesh]

My plan is to run FreeSWITCH containers as a service on a Docker Swarm.
What I want to understand is:
What would happen if I make a request via ESL (let's say I want to execute certain commands for a channel) and that channel does not exist on the instance?
Is there a way where I can route the request to a specific FreeSWITCH? Or something that sends it to all the available containers in the swarm and outputs only the valid response?
I am sorry if this is not the right place to ask this question, but, any help would be greatly appreciated.
